医院内部风险基金制度与病人安全初探

医疗活动本身存在着不确定性和相对确定性一对内在矛盾,由不确定性引发的医疗过失等是影响病人安全的主要因素。在目前以医院为管理主体的前提下,建立医院内部风险基金制度,提高医务人员的执业风险意识,减少医疗过失的发生,是保障病人安全的一种尝试。     

浅谈影像诊断思维特征

人类的科学思维方式是一个多层次、多形态、多要素的系统。对每一种事物的认识过程都有特定的思维方式。疾病的诊断是一个主观反映客观的认识过程,反映客观的真实程度愈高,诊断的正确性愈高,而客观真实性的再现,在相当程度上取决于人的主观意识,人的主观意识又通过人的思维活动来实现。所以,人的思维在疾病的诊断中占有重要意义。而医学影像诊断思维又有其特点,即以形象思维为先导,以逻辑思维来归结,又有非逻辑思维闪现,如直觉、灵感、经验思维。只有各种思维形式有机的交叉运用,才能得出最接近真实的诊断结论。     

Variation in coordination of a discrete multiarticular action as a function of skill level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.     

中学生颜色内隐学习特征的实验研究

该研究以48名中学生为被试,分别用色块串和色词串为材料,设时间变量（单元）以了解学习的详细进程,研究了中学生颜色内隐和外显学习的特点。结果发现：（1）非言语材料（色块）较言语材料（色词）更适合于内隐加工;（2）时间变量上整体呈递增趋势,称长时功效。内隐学习的长时功效在教学上有重要意义;（3）指导语上存在主效应,内隐学习优于外显学习,即内隐学习在不同材料上的优势效应依然存在。     

Development of the Real-Time Subjective Emotionality Assessment (RTSEA) system

A new Real-Time Subjective Emotionality Assessment (RTSEA) system was developed for this study. The system is composed of two parts: an emotionality input and evaluation parts. An experiment was conducted in order to investigate the effectiveness of the RTSEA system. The present study compared Galvanic Skin Response (GSR) with the RTSEA by presenting 28 subjects with pictures that aroused either positive or negative emotion. Following the experiment, a subjective assessment using a questionnaire was given to the same subjects. According to the correlation coefficients, changes of the RTSEA had strong correlations with the changes of the GSR. Also, the questionnaire results showed marked similarity to the average responses of the RTSEA. In conclusion, the most remarkable characteristic of the present system is that it not only assesses the average emotionality when stimuli are presented, but also shows the trend of change in emotionality over time.     

智力结构的分化假设

该文探讨了智力结构随能力、年龄等个体差异而变化的可能性。认知分化假设认为,能力水平更高的人有“更多”的智力,其智力结构中g因素的作用随IQ水平的增加而递减。年龄分化假设指出,从童年期到青年早期,g因素在认知能力中的作用随年龄的增加而减小;相反,从青年早期到成年晚期,g因素的作用递增,智力结构中其他因素的数量和重要性则递减。该领域未来的研究应当解决测量和评估工具的问题,扩大被试的能力水平和年龄范围     

整合人格与智力:个体差异研究的新思路

整合人格与智力的关系是个体差异研究的一种新思路,该文重点介绍和剖析了三种人格—智力关系的理论模型,包括Ackerman的特质组合模型、Brand的“双锥体”模型以及Chamorro-Premuzic的交互作用模型.作者认为,人格与智力的整合研究必须从研究方法、理论层面和测量工具等方面加以改进和完善,必须揭示影响两者关系的中介变量和潜在变量,充分体现这种关系的动态性.     

睡眠对恐惧学习的影响及其认知神经机制

睡眠问题可能会诱发恐惧相关情绪障碍(焦虑、创伤性应激障碍、恐怖症等),研究睡眠影响恐惧学习的认知神经机制,有助于增强对恐惧相关情绪障碍的预测、诊断和治疗。以往研究表明睡眠剥夺影响恐惧习得和消退主要是通过抑制vmPFC活动,阻碍其与杏仁核的功能连接,从而导致恐惧习得增强或是消退学习受损。进一步研究发现睡眠不同阶段对恐惧学习相关脑区有独特的影响:剥夺(缺乏)快速眼动睡眠会抑制vmPFC活动、增强杏仁核、海马激活,导致恐惧习得增强,消退学习受损,此外边缘皮层的功能连接减少破坏了记忆巩固(恐惧记忆和消退记忆);而慢波睡眠主要与海马变化有关,慢波睡眠期间进行目标记忆重激活可促进恐惧消退学习。未来研究需要增加睡眠影响恐惧泛化的神经机制研究、及昼夜节律中断对恐惧消退的影响,以及关注动物睡眠研究向人类睡眠研究转化中存在的问题。     

工作情境中的人格研究：回顾与展望

人格研究对任何层次的组织行为都产生了深远的影响,大量元分析都显示了人格特质对工作动机、工作绩效、员工幸福感、压力与应对、团队效能、冲突与谈判、权利与政治、领导以及反组织行为等组织行为指标具有良好的预测力。但是人格研究在组织中的应用因为人格测验的效度和被试在测验中“作假”而饱受争议和批评。人格理论的拓展及其跨文化的适用性,人格特质的负面作用以及结合组织情境的动态研究都是今后研究值得关注和探索的方向。     

论概念空间

人类的认识结果往往是以概念的形式加以确定和传播,因此,概念本身就成为我们讨论人类认识的主要对象,哲学的反思正是我们对概念本身的研究活动.
